Title:
SEQUENCE CONTROLLER
Document Type and Number:
Japanese Patent JPS62259103
Kind Code:
A
Abstract:
PURPOSE:To avoid increase of the number of input/output circuits and cables despite the increase of the number of shared power generators, by using a common sequence controller to decide a specific power generator to be started and delivering the sense signal only to the sequence controller for said power generator. CONSTITUTION:A power generator 1 or 2 is decided by a common arithmetic unit 31 of a common sequence controller 3 for both generators. A sense signal output circuit 33 delivers the sense signal to its corresponding sense signal line 81 or 82. Then a common input/output circuit 32 is connected to an input/ output circuit 11 for generator 1 of the corresponding sequence controller 1 for generator 1 or an input/output circuit 12 for generator 2 of a sequence controller 2 for generator 2 via a data signal line 7. Both circuits 12 and 22 are connected to each other via the line 7 while both generators 1 and 2 are working. In such a constitution, it is not required to increase the number of input/output circuits at the side of the controller 3 as well as the number of lines 7 despite increase of the number of power generators. Thus it is possible to obtain a simple and compact system constitution.
